Kate Middleton, like Michelle Obama, is known for wearing chic but affordable couture. But she went all out for the Queen's Diamond Jubilee. Find out how much the pricey pink dress cost at :25 in the video below.

The Duchess looked pretty (but plain) in the pink-pleated dress as she mingled with members of the British and foreign royal families at Windsor Castle. The dress was by Emilia Wickstead, according to The Mirror.

But little sister Pippa rocked her own pink dress over the weekend -- almost the same Issa wrap dress Kate wore to announce her engagement to Prince William in 2010! Pippa's dress goes for about $711, and it has us wondering... who looks prettier in pink: Kate or Pippa?

No, I am sorry you misunderstood. They are both beautiful and entitled to respect. I guess I just meant that since Kate is married and the future Queen, single men should focus their attention on Pippa. Kate is :"off the market."

I dont know exactly, but in particularly those pictures, I like Pippa's better. So I am not saying Pippa looks better generally. And anyway in those pictures theyre pretty much the same style (the dresses), so lets just say I like Pippa's dress colour better.
